Energy Deficiency, Training Frequency, and Beginner Gains (Episode 62)
Key Moments
Podcast discusses the MacroFactor nutrition app, the shakiri richardson controversy, diet recovery, training frequency, and statistical interpretation.
Key Insights
The MacroFactor nutrition app is nearing completion and is set to launch soon, with beta testing starting shortly.
The discussion around Shakiri Richardson's marijuana ban highlights differing perspectives on sports regulations and personal freedom.
Relative energy deficiency in sport (RED-S) and metabolic adaptation share overlapping concepts, focusing on low energy availability and its detrimental effects.
The effectiveness of training frequency for strength gains in trained individuals is minimal, suggesting individual experimentation is crucial.
Beginner gains are possible even after years of inconsistent training if a trainee significantly improves their approach to nutrition and programming.
Short, frequent cycles of bulking and cutting may be less effective than a more stable, progressive approach due to potential for increased fat gain and metabolic disruption.
MACROFACTOR NUTRITION APP UPDATE
The episode begins with an update on the forthcoming nutrition app, MacroFactor. The app is in its final stages of development, with beta testing scheduled to commence soon and a projected launch in September. A "coming soon" page with more details is available on the Stronger By Science website, with a link provided in the show notes for interested listeners.
SHAKIRI RICHARDSON CONTROVERSY AND PERSPECTIVES ON RULES
A segment addresses the controversy surrounding sprinter Shakiri Richardson's ban from the Olympics due to a positive marijuana test. While humorously framed with a 'Christian perspective' on rules, the hosts acknowledge the frustration and unfairness of certain regulations. They subtly critique the ban, particularly leaving Richardson off the relay team, while also offering a perspective on her youth and potential for future success.
RELATIVE ENERGY DEFICIENCY AND METABOLIC ADAPTATION
The discussion delves into relative energy deficiency in sport (RED-S) and metabolic adaptation. These concepts are highly overlapping, stemming from insufficient energy availability. RED-S often focuses on sport-specific outcomes like bone health and stress fractures, especially in endurance athletes. Metabolic adaptation typically emphasizes physique-related dieting, focusing on reduced energy expenditure, dysregulated hunger cues, and challenges with maintaining lean mass. Both involve the body's hormonal responses to prolonged low energy states.
NON-PHARMACOLOGICAL STRATEGIES FOR ENERGY DEFICIENCY RECOVERY
A research review highlights non-pharmacological strategies for treating RED-S. Beyond the obvious advice of caloric surplus, training volume reduction, and fat gain, the paper suggests other modifiable factors. These include distributing energy intake more evenly throughout the day, prioritizing carbohydrate availability, managing psychological stressors, and effectively managing training stress. These strategies can aid recovery when immediate, drastic changes are not feasible or desired by the individual.
TRAINING FREQUENCY AND STRENGTH DEVELOPMENT
A meta-analysis on training frequency in trained populations found minimal to no significant impact on strength gains. While previous analyses suggested a slight benefit to higher frequencies, this newer study, focusing exclusively on trained individuals and using volume-equated protocols, showed negligible effect sizes. The authors emphasize that while average effects may be small, frequency can be a variable with high individual variability, suggesting personal experimentation is key for optimizing training.
BEGINNER GAINS AND TRAINING AGE
The concept of 'beginner gains' is re-examined, asserting that substantial rapid progress is possible even after years of inconsistent training, provided significant improvements are made to nutrition and programming. Training age is discussed as better reflecting the quality of training rather than just chronological years. The conversation touches on how puberty significantly impacts muscle-building potential, advising younger lifters to wait for peak pubertal development before making definitive judgments about their training response.
EVALUATING SHORT BULKING AND CUTTING CYCLES
Short bulking and cutting cycles are analyzed, with a leaning against their effectiveness. The hosts question the premise that shorter deficits reduce metabolic adaptation, suggesting deficit size and duration are more critical. They also argue that frequent cuts might create a problem by necessitating them due to aggressive bulking phases. A preference for stability, predictability, and a slower, progressive approach to body composition changes is advocated, particularly for drug-free individuals.
STATISTICAL INTERPRETATION ERRORS IN FITNESS DATA
Common errors in interpreting statistics, particularly within the fitness community, are discussed. These include misunderstanding ANOVA interactions, inappropriately grouping continuous variables (like splitting subjects into 'high' and 'low' responders based on medians), and misinterpreting overlapping error bars as definitive proof of no significant difference. The importance of understanding correlation vs. causation and the limitations of RCTs for certain research questions are also highlighted.
ENERGY DENSITY OF FAT VS. MUSCLE
The energetic difference between fat and muscle is clarified. Fat tissue is about 4.5 times more energy-dense than lean mass. This means simultaneous fat loss and muscle gain, while potentially resulting in weight stability, would occur in a caloric deficit. Conversely, gaining fat while losing muscle would lead to weight stability but a caloric surplus. This distinction is crucial for understanding body composition changes.
TRAINING SCHEDULES AND CAFFEINE CONSUMPTION
A question about late-afternoon training and caffeine use is addressed. Given caffeine's half-life, consuming it close to bedtime (within 5-6 hours) is advised against due to potential sleep disruption, even for habitual users. The perceived ergogenic benefits of caffeine from such use are deemed less significant than the value of quality sleep, leading to a recommendation to skip the caffeine in specific late-day training scenarios.
CARDIO ROUTINES VS. COMPETITIVE ENDURANCE EVENTS
When discussing cardio routines, the hosts share their personal approaches. One host engages in long walks and plays basketball, while the other focuses on swimming proficiency, having previously completed a sprint triathlon. Both emphasize making cardio enjoyable and sustainable, rather than strictly adhering to numbers. Competitive endurance events like marathons have not been undertaken by either host.
THE CONSTRAINED ENERGY EXPENDITURE MODEL
The constrained energy expenditure model, which suggests that beyond a certain point, increased physical activity does not proportionally increase total daily energy expenditure, is explored. Possible mechanisms include increased sedentary time or slight downregulation of resting metabolic rate. The hosts caution against the negative interpretation that exercise is pointless for energy expenditure, noting that for most sedentary individuals, increased activity will likely increase TDEE, though not always on a one-to-one calorie basis.
MEDIA RECOMMENDATION: WHAT WE DO IN THE SHADOWS UNIVERSE
The episode concludes with a media recommendation for the 'What We Do in the Shadows' cinematic universe. The original film and the subsequent TV show are highly praised for their humor and lightheartedness. A new spin-off series, 'Wellington Paranormal,' is also highlighted as being delightful, particularly noted for the charming New Zealand accents, making it a recommended watch for low-stress comedy.

Energy Density Comparison: Fat vs. Lean Mass
Data extracted from this episode
| Tissue Type | Energy Value (per kg) | Relative Energy Density |
|---|---|---|
| Adipose Tissue (Fat) | ~9400 kilocalories | 4.5x more dense |
| Lean Mass (Muscle) | ~1800-1900 kilocalories | 1x |
Common Questions
The hosts sarcastically criticize the ban as 'dumb,' particularly the decision to exclude her from the 4x100 relay after her 30-day ban for the individual event. They argue that rules are rules, but the extension to the relay was 'messed up.'
